Chicago Stock Exchange

CHX is an integral part of the National Market System offering
competition to all U.S. equity markets. The exchange enables clients to
transact business in virtually all New York Stock Exchange and NASDAQ
listed issues.

“Informatica Ultra Messaging is now the gold standard for Chicago Stock Exchange’s matching, order delivery and market data systems.”

— Bob Garrett, Vice President, Application

Development, CHX

Business Need

Process orders and market data in sub-millisecond response times, and at lower cost.

Ensure CHX continues as a destination for hedge funds, market makers, professional and active individual traders that require immediate and automated execution.

Satisfy the needs of traditional broker-dealer clients and the individual investors traders represent.

Challenges

Some market data channels were getting 5,000 messages per second one day, and up to 8,000 messages per second the next.

Ambition was to process any of these inputs at the advertised rates, with no queuing.
